Abstract / Excerpt:

Voice over Internet Protocol (VoIP) is fast emerging technology predicted to soon replace Public Switched Telephone Networks (PSTNs). The protocol most common in VoIP - H.323 which was established by the International Telephony Union (ITU) is being used to develop applications for the entries in the network such as the gatekeeper. However to develop such applications would require the developer to hard code them using C/ C++. In addition, the library of the H.323 protocol cannot be referenced by Rapid Application Development (RAD) tools because it is not Object Linking and Embedding (OLE) based. With OLE, it is possible to dynamically link files and applications together. An OCX is an OLE custom control, a special-purpose program that can be created for use by applications running on Microsoft's Windows systems. The proponents developed a reusable H.323's gatekeeper and OLE custom control component and a sample gatekeeper application using the OLE.
